Cancel My ShortsWave Subscription And Get Me A Refund ASAP

I have been repeatedly charged for a Shortswave subscription that I have been trying to cancel for weeks, and I am unable to stop the payments or reach effective support from the company. I originally started the subscription through the Shortswave app on my iPhone and only intended to use the product for one week. Despite this, I am now being billed on a weekly basis, and these Shortswave charges appear as recurring payments on my Visa card. The unwanted weekly charges started on 7 June and have continued since then, reaching a total of approximately 179.90 USD beyond the first intended week. The subscription does not appear anywhere in my Apple ID subscriptions list, so I cannot cancel it from there. Inside the Shortswave app there is no option to cancel or manage the subscription; instead, the app directs me to the iOS subscription settings, where the subscription is not listed at all. I also tried deleting the app from my phone, but the charges have continued. I have contacted the company multiple times at [email protected] but have not received any response. During sign‑up the app did not clearly ask for or show my email address, which makes it very difficult to manage or cancel the subscription and to identify my account, while the payments keep being charged to my card without my consent. I request that my Shortswave subscription be cancelled immediately, that I receive a full refund of all payments charged after the first week, and that I am provided with a clear written confirmation that my account has been closed and that no further charges will be made to my card.
